ok...i know the RB 3inch DP will not fit onto the stock catback...ok...heres my question.....i have the RB2.5DP/MP......recently aquired a catback from the 3inch turboback......will the 2.5inch bolt onto the 3 inch catback?......

 

oh yeah....i have the presilencer from the turboback also....

 

i'd say no

 

haha...thread ends here......

 

are you talking about the flanges or the lengths of the DP?

 

both....right now i have the 2.5 DP mounted.......can i use the 3 inch catback with the MP or do i need to use the presilencer thats with the 3 inch system....or would it not bolt up at all..

 

Eh, it *might* but I'm doubting on how well it will. You'd probably want some type of adapter for it if you did, like 2.5 to 3" adapter between the presilencer and catback, but then again you don't really have room for it. Since you have the presilencer for the 3" catback already, I'd say either get a 3" downpipe or have one made. Go for 3" full exhaust

 

everything is on now...i ended up putting on the 3inch turbo back....boost creeps like theres no tomorrow.....if the creeps keep up...there might not be tomorrow!...
